10 DR. B. SEEMANN ON THE CRESCENTIACE.E. 
According to Perville, who found this species at St. Marie, in the N.E. of Madagascar, it 
is a shrub 12-15 feet high, with rose-coloured flowers. The specific name " tetragona " does 
not apply well to this plant, since better specimens than those at DeCandolle' s disposal 
show that the normal number of the leaves, and the consequent edges of the branches, is 
seven, and that only weak specimens have square branches. The hard, acute, persistent 
scales occasionally met with in this species, and regarded by Bojer as stipules, appear to 
me (as supposed by DeCandolle) to be abortive leaves, somewhat analogous to the scales 
on the trunk of Cycas.

Easily distinguished from Colea tetragona, its nearest ally, by its opposite, never verti 
cillate leaves, and from all other Coleas by its racemes clothed with foliaceous bracts 
By its bracts it approaches Colea involucrata, Boj. It is necessary to add, that Bojei 
distributed specimens of Colea floribunda, Boj. under the name of Bignonia decora 
which has given rise to some confusion, leading in some herbaria to the error of attaching 
the name of Colea decora to the wrong plant.

The fruit of this species, though unknown to both DeCandolle and myself, was pro- 
bably seen by Bojer, and induced him to place the plant with his genus Colea 9 in which
